`.Application led January 2, 1926. Serial No. 78,796.'

To all whom t may concern: Be it known that I, JAMES' F. HINns, acitizen of the United States of America, and a lresident of Lakewood, inthe county of 5 Cuyahoga and State of Ohio, have invented certain newand useful Improvements' in Mold'Containers, of which the following is afull, clear, and exact description.

So far as I amawaresnap flasks and jackets in use prior to my invent-ionhave all been open to a variety of objections, principally the high costof providing a permanently rigid flask or jacket having a finishedinterior, the inability to construct '15 a finished interior fiask orjacketwith rigid corners at a commercial cost, and the 1nability of anyone flask or jacket to function yin all the various types of molding. Myinvention provides a mold container free from In the drawingsaccompanying this specification and forming a part of this application Ihave shown, for purposes of illustration, one form which my inventionmay assume, but I have illustrated this form, only as 'applied to thedrag section of al ask since its application to the cope section of afiask, or to a jacket, or to any other mold container, will be obviousfrom. the disclof sure relating to the fiask drag section.

In these'drawings:

Figure l represents a preferred method of forming the flask, whileFigures 2, 3, and 4 show alternative forms of corner construction.

The present'application is a continuation in part of my copendingapplication Serial Number 720,218, filed June 16, v1924.

In constructing the fiask drag section heren in shown Isfirst constructa form 3l, preferably madeof wood, and having its exterior of the exactform desired for the interior of the fiask section, and I then .assemblev aboutthis form 31 a pair of drag side plates 5 32' and a pair ofl dragend plates 33 of thel proper dimensions to exactly encircle the form v31when their ends are tightly abutted, preferably formed of cast aluminum,having their inner-surfaces completely finished bemold container, wou dof course fore assembly, and each provided-at-eachend wlth a recess 34arranged to communicate -and cooperate with the adjoining recess of theadjacent part. I then clamp these members 32 and 33 tightly in positionabout the form 31, close the lower ends of the recesses 34 in anysuitable manner, as b resting the lform and members upon a suita lelflat plate,

and then pour into the recesses 34 molten metal 35 which may be lead orbabbitt but it preferably the same material as the flask members andtherefore preferably aluminum. I then maintain the members 32 and 33 inposition about the'form 31 until the metal 35 isset after which themetal 35 is effective to firmly and fixedly permanently` 06 retain themembers 32 and 33 together and form the members 32 and 33 into a unitaryand integral flask drag section 36.

A jacket, or flask co .e section, or anyother be constructedf in thesame `manner, but in con` structing; the sections of a flask I prefer toextend t e form -31 as shown and tov construct the additional sectionsabout the same form above the drag section 36.

Undercertain circumstances I refer to form the corner joint as shown ini re 2 wherein each recess 34 is interrupte by 'a plurality ofvertically spaced cross pins- 37 which are embraced bythe metal 35v andserve 80 as an anchorage toabsolutely prevent the metal-35 from pullingout `of the recesses 34. In other4 cases I find it entirel 'suiiicientto use the construction shown inl igure 3 wherein each recess 34 isinterrupted byA a pluralit of vertically spacedlugs 38 u on which t emetal 35 may grip. In still ot er cases 'I- find it entirely safe toutilize the construction of Figure 4 whereinI' omit all interruptions'inthe recesses 34 and'rely -solely'lupon the roughness 'of the-walls ofthe recesses 34, as cast, -to provide the desired, grip between .themembers and the metal 35. Under certain circumstances it might alsobe`desirable to .taper the walls of the recesses 34 to provide a dove-tailconstruction but so .far Ihavenot found such a construction necessaryand I' prefer.- to

omit it, as I`also prefer to omit the pins 37 and lugs 38' whenpossible, all in order to' reduce the costof manufacture.

' In actual practice, however, I find desirable eitherthe pins 37 or thelugs 38, pref.

- erably the pins 37, because byl interconnecting the interior andexterior walls l39 and 1,0 they permit these walls being made thiniferand therefore-lighter.

Afterv the mold containers have .been formed in this way any sand stripand registering devices and other accessories may be added `thereto inany manner found convenient.

From the above it will be obvious to those skilled in the art that Ihave disclosed herevin a mold container superior to anything lheretoforeused. Itwill also be obvious to those skilled in the art thatthe-particularA embodiment of my invention herein shown" and describedmay be variously changed and modified without departing from the scopeof my invention or lsacrificing thel admol vantages thereof.

It will therefore bel understood that the disclosure herein isillustrative only and that Vmy invention is not limited thereto.

I claim:

1. A joint securing'togethertwo substantiall non-integrated members of ametal container, comprising cooperating joint sections formed one-oneach of said members, and abutting, and formed "to pro- .'vide a* recessbetween said sections, and a vmetal tie cast in said. recess andeffective `alone to hold said members firmly and fixedly rigidlyassembled.

.2. A ask section comprising a plurality of nonintegrated metal members'arranged in an annulus with each pair of adjacent ends abutted andcontainingfa .recess lying partly in each member, and metal ties cast,1n said recesses l'and effective to hold said members firmly and xedlypermanently assembled into a rigid flask section. v

3. A joint securing together two members i of a metal mold container,comprising, cooperating joint sections formed one on-'each of saidmembers, and abutting, and formed to provide a recess between saidsections, and a metal tie cast in said recess, and 'lying entirelyexteriorlyof the inner walls of said 5./A flask section comprising aplurality iiswis ly and fixedly permanently assembled into a rigid flasksection.

6. A joint securing together two members of a metal mold container,comprising cooperating joint sections formed one on each of saidmembers, and abutting, and formed to provide` a recess between saidsections elongated longitudinally of the axis of said joint, and a metaltie cast in said recess and vacting to hold said members firmly andfixedly rigidly assembled.

7.
